Kern Paillard for Bolex RX 18-86mm f2.5 Vario- Switar EE Cine Lens C-Mount , photos /videos of the actual lens. This lens is pre corrected  for exposure on the Bolex H-16 Rex Reflex models. 

It is working and in excellent shape with respect to zoom and aperture in manual mode.  See the photos and videos

The one element I was unable to confirm is automatic aperture control by the side mounted meter. This version doesn't have a battery check, but even under bright light I could not see any movement automatically by the aperture; I am not totally familiar with the mechanism ; as a result this aspect is "AS-iS. Aperture, zoom, and focus are all smooth and excellent.  Includes the hood. 

What is varified is the zoom works fine, aperture control works fine in manual mode; their is no fungus but there is minor dust and a bit of haze only visible under scrutiny.  As you can see in the photos and video image quality is very good, so there should be no problem in use for actual film use.
